Hi Sonette,
When I re-read your attachment, I notice you still have active students for
that assessment. But according to the piece of code you pointed out, it
returns false only when there is no active student:
*The rest of the code is then not executed because false is returned:*
Iterator iter = scores.iterator();
//log.info("Has this many agents: " + scores.size());
*if* (!iter.hasNext())
*return* *false*;
So I am not sure if above code is the cause of you issue, and not sure if
SAM-848 is the right fix. Please confirm.
Thanks,
Karen
